Wifi rev,2 and bluetooth classic

After a little search on this forum and the web, and though in the presentation of the board BT classic
is declared supported, I could not find any example, explanation or detailed comment on using BT classic with Arduino Wifi rev. 2. Can anybody suggest how to find information on this subject? Thanks.

I believe the information in this thread will also be relevant to the Uno WiFi Rev2:

Although that thread is about the Nano 33 IoT, it uses the same "NINA" ESP32-based module as the Uno WiFi Rev2. Bluetooth classic support is a matter of the firmware running on the NINA module, rather than anything specific to the primary ATmega4809 microcontroller on the Uno WiFi Rev2.

Thanks to both of you for the pointers. Indeed a simpler tutorial or guiding examples would help.

it is hack, which replaces the Arduino firmware in the NINA module with a super simple esp32 arduino sketch to relay command to esp32 SDK. so there is no WiFi and no BLE. only classic Bluetooth is possible then.
